Description

MODULAR COMPLEX “LITORAL

FOR ENGINEERING-GEOLOGICAL RESEARCH

Shelf Transit Zones

The device relates to the constructive implementation of the means of production of engineering and geological research on the basis of a special watercraft and can be used for drilling and seismic exploration in extreme shallow water in inaccessible transitional (transit) water-land zones.

Traditionally, engineering-geological and (or) geophysical work at sea is carried out using specialized research vessels (NIS) 1 - 6. Such NIS, as a rule, is equipped with technological equipment for carrying out a particular type of engineering and (or) geophysical work, in this case, vessels can be made in the form of a shallow-sitting vessel (see, for example, 1, 6) with a change in bow draft for their use in shallow water areas (About 5 m), which is very difficult for typical NIS (see, for example, the geophysical description vessel 4 or a catamaran vessel for environmental monitoring of water areas 5) of the mid-deep shelf (50 150 m). Standard pontoon ferry-bridge devices 7, including block floating structures, also cannot satisfy the specifics of work in transit zones.

The well-known complex 3 includes a rational block design, however, it is designed to equip offshore stationary platforms and is therefore very complex and cumbersome, the use of such complexes in transit zones is technologically and economically impractical.

Complex 2 for carrying out work in the water areas, including a watercraft with equipment located on it, is intended mainly for cleaning works in shallow water.

Shallow-water transitional (transit) zones require special equipment and adequate construction of geophysical tools taking into account the complex criterion “complexity - cost-effectiveness.

In 1, an attempt was made to develop a marine seismic complex for transit zones on the basis of a vessel of a special design (shallow-sitting barge with the ability to change bow draft) and rational placement of the main components of technological equipment.

The well-known marine complex 1, adopted as a prototype, contains a vessel equipped with technological equipment, which is designed for seismic work in transit zones.

Due to its specificity, complex 1 cannot be used for various engineering and geological works, for example, for drilling. At the same time, as practice shows, effective and high-quality engineering and geological work in transit zones can only be carried out using a light modular complex assembled from individual elements that can be transported not only by water, but also by road or rail.

The essence of the proposed technical solution is to create a collapsible modular complex for engineering-geological studies of transit zones on the basis of a self-propelled (or non-self-propelled) multihull floating metal pontoon, the elements of which (including the pontoons' hulls, interconnections and the working deck) are unified and allow assembling the complex from several modules with placement on a team of unified elements of the working deck of technological equipment of various design purposes (geophysical, drilling, cargo, etc.).

The main technical result of the proposed complex is its rational design, which improves manufacturability, economy and ease of maintenance (including assembly / disassembly) and, as a result, the effectiveness of engineering and geological studies of shelf transit zones. The unification of the elements of the modular complex allows to realize the versatility of the craft for the production of various types of research and production work in transit zones.

The technical result is achieved as follows.

The Litoral modular complex (Litoral is the generally accepted name among specialists for the transitional (transit) water-land zones) for geotechnical studies of shelf transit zones, includes a watercraft equipped with technological equipment.

Distinctive features of the Litoral complex is that the watercraft is made in the form of a self-propelled or non-self-propelled multihull pontoon module containing at least two hulls connected by interconnections-bridges, and a prefabricated working deck for placement of technological equipment, which

made of the same unified elements and is the foundation for removable block processing equipment for the installation of modular complexes for special purposes, such as geophysical, drilling or cargo. The shells of the pontoon module are made with bow and stern gaps and an oval cross-section and are divided by bulkheads into waterproof compartments, the interbody links-bridges are rigidly connected to the shells of the pontoon module and elements of the prefabricated working deck by means of bolt fasteners. Moreover, the multi-hull pontoon module, interconnect links-bridges and the working deck are made of collapsible elements that meet the weight and overall requirements for transportation by road or rail.

In addition, the Litoral modular complex is characterized in that the pontoon module is made in the form of a catamaran, trimaran or multi-hull system and is equipped with means for assembling a complex of several modules, for example by means of lock or bolt connections.

In the particular case of implementation, the technological equipment of the geophysical complex includes a container-type laboratory room, a high-pressure compressor with a receiver, a diesel power station, as well as a geophysical winch with a seismic scythe and guiding rolls.

Technological equipment of the drilling complex includes a drilling rig and technological racks with drill pipes and is additionally equipped with spacer piles to fix the drilling complex at the drilling point.

In the particular case of the implementation of the cargo modular complex, its technological equipment includes a crane.

technological racks for casing and drill pipes, tanks for fuels and lubricants.

At the same time, specialized technological equipment of geophysical or drilling, or cargo modular buildings is made in the form of removable blocks placed and fixed on the unified elements of the working deck.

In FIG. 1 presents a structural diagram of the modular complex “Litoral in the embodiment of the geophysical complex. Figure 2 illustrates the overall construction of the pontoon module in the form of a catamaran. In FIG. 3 and 4 are structural diagrams of the drilling and cargo modular complexes.

The following notation is used in the drawings: 1 - pontoon module case; 2 - interconnect communications-bridges; 3 - prefabricated work deck; 4 - unified elements of the working deck; 5 - bolt fasteners of connecting elements of communication-bridges; 6 - bulkheads in the pontoon module cases; 7 - laboratory room; 8 compressor with receiver; 9 - diesel power station; 10 - winch with a seismic scythe; 11 - guide rollers; 12 - drilling rig; 13 technological racks with pipes of the drilling complex; 14 - pin piles; 15 - crane; 16 - technological tanks for fuel and lubricants.

The technical result of the Litoral complex is provided by its modular structure and is realized during its transportation, assembly (disassembly) and work on a given program of engineering and geological research. Work with the modular complex is as follows.

Before starting work, it is determined what types of engineering-geological studies must be performed and with what technological equipment. Collapsible elements of modular

The complex is delivered to the work area by road, rail or water. Cases 1 of the pontoon module through interconnect-bridges 2 are assembled into a catamaran (trimaran, multi-hull system). On top of the buildings 1 by means of bolt fasteners 5 mounted unified elements 4 of the working deck 3 (figure 2). Bulkheads 6 in the cases of the pontoon module serve to ensure the waterproofness of its compartments. On the unified elements of the working deck 3 are placed and fixed removable blocks of specialized technological equipment designed to perform a given type of engineering and geological research. When performing geophysical work on the working deck 3, a laboratory room 7, a compressor 8 with a receiver, a diesel power station 9, a winch 10 with a seismic scythe and guide rods are mounted (figure 1). For drilling operations, the module (Fig. 3) is equipped with a drilling machine 12, racks 13 with pipes and pin piles 14 for fixing the drilling module at the point of work in shallow water. Carrying out cargo operations is ensured (Fig. 4) by technological equipment located on the working deck 3 comprising a crane 15, technological racks 16 and tanks for fuel and lubricants.

Thus, engineering and geological work in transit zones is provided by a rational modular complex, assembled from separate unified elements and transported to the place of work by any means of transport. The modular complex Litoral implements the versatility of a watercraft for carrying out various types of research and production work in transit zones, and, if necessary, the complex can be assembled from several modules using lock or bolt connections, depending on the specifics of engineering and geological work.
